You only have to install this application, create an account -totally free- and start uploading files.
Once you have uploaded the files you want, you will be able to access them at anytime from any computer. That means you can share the link so your friends can see or download them.
It works very similar to DropBox and you can upload videos, music, pictures, documents and more.
FlyffyApp can be ery helpful if you want to share files with your friends or if you want to access any file from many different computers. It's llike having an extra hard disk accessible from anywhere.
